more particularly to a machine having novel and improved means whereby a crease may be produced as desiredin the upper of a shoe to increase the aesthetic value o the shoe.

lAnother object of the invention is to provide a novel and improved machine comprising a creasing roller rotating about a fixed aXis together with a member movable toward or from the creasing roller and em-y bodying a pair of under creasing rolls in cooperation with the first named creasing roll to produce the desired crease within the work.

Another object of the invention is to provide a machine of this general character comprising an upper creasing roll which coacts with a pair of spaced under creasing rolls and wherein means are interposed be.

tween the under creasing rolls to serve as a depth gauge for the crease producedwithin the work.

An additional object of the invention is to provide a novel and improved machinev of this general character comprising an upper creasing roll with a pair of under creasing rolls, said under creasing rolls having relative axial movement together with means for constantly urging the under creasing rolls one toward the other together'with an ele ment interposed between the under creasing' rolls to maintain a set width therebetween.

- The invention consists inthe details Vofv construction and in the combination and ar-I rangement of the several parts of my improved shoe machinery whereby certain important advantages are attained and the de-v vice rendered simpler, less expensive and otherwise more convenient and, advantageous for use, as Will be hereinafter more fully set forth. p

The novel features ofmy invention willl hereinafter be definitely claimed. Q 'V In order that my invention may be the better understood, I will now proceed to describe the sameK with referenceftoV the. accompanying drawings,l wherein Figure l is a view in elevation with por!v tions broken away, of a machinecoiistru'ctf ed in accordancev with an embodiment of my invention;

Figure 2 is an enlarged vertical sectionalview taken through the device asl illustrated in Figure l, said line of section being be.l tween the under creasing rolls and distorted to show Vthe upper creasing roll in eleva,-

.Figurel 3 isa fragmentary view -in plan p illustrating vthe depth gauge;

Figure 4 is an enlarged `fragmentary `view partly in longitudinal i :section and partly; in elevation illustrating the detail mounting ofthe under creasing rolls and "f the location of the depth gauge;

Figure 5 is an enlarged :fragmentary view partly in elevation and partly in section illustrating a modified construction to come plete the crease structure ofthe upper ofa j v vso Figure 6 is a view; in perspective of anarshoe or the like;

ticle produced by my improved machinery.

As disclosed in the accompanying drawings, 1 denotes a base of suitable design and preferably formed of cast iron and which is provided at its top with a table 2 and a head `3 overlying'said table.A The head?) rotatably supports a'horizontally disposed shaft' desired` inanj l adapted to be driven in any ner as by a pulley 5 or the like.

Fixed to theshaft 4 is the upper creasing roll 6 `provided atA substantially its transverse center with an outstanding and cir-A -cumferentially disposed rib orbead 7. The

upper creasing roll 6 is positioned above an opening 8 provided in the table Qwith'the -rib or bead 7 positioned substantially `directly above anarm l0. Thearm 10 is subkstantially perpendicularl'y related to` the,l

shaft 4. and lbridges the opening 8 in lthe-,e100

table 2, theopposite end portions of said f arm 10 being secured as at 11 to the table 2, such connections preferablycomprising.'v i

applied or removed as may be desired. This removable screws so that the arm l()A can be arm l0 serves as a depth gaugegand'jina referred to.

The forward face ofwtheib-ase'l and at the I' lower portion thereof is `provided with the manner-to be hereinafter more particularly 1 spaced verticallyy disposed guides 12 beI tween which is snugly engaged the slide 14. The slide vli is maintained l.between the guides 12 by the plate 15 which vhas its o pposite lmarginal portion secured by the screws 16 or the like to the outer faces ot the guides 12, whereby the plate 15 bridges the space between the guides l2.

The lower portion ot the plate at substantially its transverse center is provided with a vertically disposed slot 17 the upper @des @3f which bein defined by an ontstemd ing'lug 18. Threaced Athrough the lug from above is abella-19, the lower end of which isadapted to contact an outstanding lugfr 20 lcarried by the lower portion ot the slide 14, said lug 2O being directed through the openinw 17. By this means the extent of upwarcniovement 0f the slide 14 maybe regulated or @Olltrolled in accordance with the necessities of practice.

The lower or bottom ends of the guides 12 are connected by the strip or elongated member21 through the central portion of which is freely disposed the operating rod 22 for the slide lei, the upper portion of said rod 22 being threaded as at 23 or otherwise. connected with the slide 14. rThe-rod 22r is adapted to have engaged tl'ierewithany means which can be employed with convenience and facility to impart downwarc moif'enient to the slide 14.

The lower taceoi the slide 14 at opposite sides of the lug 20, is provided with sockets 14 in'which are positioned the expansion coil springs 24e. The lower ends oft the springs are engaged with discs snugly iitting therein and having directcontact with the upper ends oit' the screws 26.A The screws 2Giare threaded from below through the elongated `.member or strip 21. As the slide. 14 is moved downwardly the springs are placed under compression. whereby it is` assured that uponrelease ot the pull upon the slide 1e the same will be moved upwardly as desired. The lower ends ot the screws 26 are preferably pro videdI with lrnurled heads 2 7 to facilitate the, desired rotation, thereo-il to regulate the tension. of the spriirgs 24. as mayk be ri quired..

The upper portion ot the slide 14. is pro--k videdl with av pairot' upstandinp;r aligned. bearings28 which slidably support the shatt 29, said shaft 29. being in parallelism with the shaft 4 heretolorereferred to and posh tioned directly therebelow. Theupper por; tiOll Q the. slide lfis provided with an arin 30 1, teriniuating,t in. an upstanding. bearing 31y to4 provideA air additional support for Vthe shaft 29;.A

0f Seid.- Shat are the under. cieasnsfrolls which are constantly urged4 one toward the.- otherthroughthe xinstruinentalii-,1y oftheexpansible. members4 33 herein. disclosed as coil spring-s and encircling the shaft 29,-each of 4said Vmembers or springs being` interposed between a. roll 32 and tension collars 31% fixed to the shaft.' The rolls 32 underlie the opposite marginal porti-ous of the upper roll 6 and are arranged at opposite sides of the arm or depth gauge 10 hereinbetore referred to. interposed between the rolls 32 is a spacing collar 35 which serves to maintain a set width between the under rolls 32 to protect the roll 6.

The end portions of the shafts Lland 29 rib or bead 7 of the upper adjacent the pulley 5 are' provided with the` coacting gears 36 whereby the desired rotation inay be imparted to the rolls (3:

and 32.

My improved machine as hereinbetore-v described is particularly adapted for use in producing` in a desired portion oit the upper 4ot a shoe an outstanding` crease to. enhance theaesthetic value of the shoe, said crease a being produced in; the work N by the rolls.

(i and 32. After the crease has been produced a reinforcing` cord I) is placed there in and the cord is maintained in applied position by a rubberized fabric strip @vork the like.

The work W, in. producing the crease passed between the rolls 6 and 32 andinv order to facilitate the application or removal ot the work, when desired the slide 14: may be depressed but, as hereinbeforeset forth, the under rolls 32 will be con# staiitly urged toward the rolls 6 by the action ot the expansible members or springs 24:. The crease produced is assured ot a fixed depth throughout its length by thearrn or gauge 10 which is positioned directly Figure 5 of. the accompanying; drawings'.

illustratesr a further embodiment ot my ma chineand which is adapted to roll down theI cord b and the strip c and wherein:they flat-1 under rolls 32* are mounted upon: the shaft' 29 in lieuof the rolls 32;` and mounted upon the shaft 4 in lieu o-,theu-pper'rolls (iris a relatively broad pressure roll? i6` but. aside@ fromi these changes the ina-chine is: con-` strueted and operated inthe saine manner as hereinbetore; described.
